1. A central stem having rediating angular arms whose farther parts are directed doWnwardly in spaced relation, a sleeve slidably mounted on said stem below the inner parts of said arms, detents pivoted on the lower terminations of said arms to swing from positions parallel thereto to positions outwardly angularly relative thereto, and operating connections linkedly connected between said sleeve, said arms, and said detents. Y

2. A central stem having radiating angular arms extending from the upper part of said 'stem in cruciform shape and with their farther parts bent downwardly in parallel relation to the stem, a sleeve mounted slidably on said stem below the radiating parts of said arms, detents pivoted on the lower terminations of said arms to swing from positions parallel thereto to positions angularly outwardly therefrom, and operating connections linkedly connected between said sleeve, said arms and said detents.

3. A central stem having radiating angular arms extending from the upper part of the stem and with their farther parts bent downwardly in parallel relation to the stem, a slidable sleeve on said stem, each arm ing composed of parallel bars united at their lower terminations with a wedgeshape, detents pivoted between the lower parts of said arms to swing to and from positions parallel thereto to posiiions angularly outwardly therefrom, and operating connections linkedly connected between said sleeve, said arms and said detents.

4. A central tubular stem having projecting arms at its upper end bent downwardly in transversely spaced relation, each arm being composed of spaced parallel bars united at their lower ends, a sleeve mounted slidably on said stem below the projecting 'parts of said arms, detents pivoted between the lower said arms 10 swing to and fro outwardly therefrom, bell-crank levers pivoted between the upper parts of said arms, links connected respectively between said levers, said sleeve and said detents, and means for shifting said sleeve on said stem in one direction.

In testimony whereof I aifix my signature.
